摘要

试验证明

钾不仅影响铸造Al-Si合金中Si相的形核过程

而且影响其生长过程

钾使工业用Al-Si合金的凝固方式由内生生长转变为外生生长

作者也用电子探针分析了钾在Al-Si合金中的分布。

Abstract

The experiments have been carried out on commerially pure cast Al-Si alloys It showed that addition of K affects both nucleution and growth of the Si phase. The solidification type of eutectic Al-Si changes from endogenous to exogenous by addition of K. The distribution of potassium has been found in Al-Si alloys by EPMA.
